JMP 8 Help: Missing Data Point (Resolved)

I am a student who recently started using JMP 8 to create data tables and graphs. I need to make a Fit Y by X graph for a data table, but one of the points refuses to show up on the graph. I have tried adjusting the X-axis and Y-axis scales and redoing the entire thing over again, but the point--which would be (655, 0.074)--does not appear, even though it is entered into my data table. When I create a line of fit for the points, the line stops at the point before the missing one (595, 0.228) and does not extend any further. Does anyone know a way I might get the point to appear?

Also: When the graph is first generated, the X-axis scales only to 600 (so obviously you cannot see any points beyond 600, including one at 655). I have to manually rescale the X-axis to, oh..at least 700..but the point at 655 still does not show. The point at 655 is the last of 6 points. Could this be why it's not appearing?

I am not used to using JMP 8, and the program and I are not getting along well yet! Any help will be truly appreciated.

It sounds as if you have inadvertently excluded the row containing that last data point.If you really have only 6 data points please post them all, and also please post the equation you get from fitting a line to your data.

Ah! It's seems to be working now; I have my point! When I closed down JMP and the data table and then opened them up again, the row that contained the missing data point had the X (655) in the first column, but no Y in the second column. I guess somehow it didn't register that I typed that last entry in...or something...but I typed it again, and this time it worked.
